If I understand correctly, this will first print the "zerror" variable,
and then the content of here/body_content. I want the error to show in the
body of the form (inside body_content). anyway, I solved it like this:

<td tal:define="zerror options/zerror" 
	tal:content="structure python:here.body_content(zerror = zerror)">
	budy content
</td>

now I can call index_html from the script and add tal:condition (not shown
above) to test for the existence of "options/error" and call body_content
like the example above.

thanx
